Changes the value of various static limits in the Portals4 netmod, based on experimentation results and suggestions from collaborators. 1. Bump most ni_limits from 32K to 64K. These limits relate closely to queue depth. We can reasonably expect to support a queue depth of 64K. 2. Limit issued origin events to 500. This translates to sending ~250 operations to Portals at a time, which over IB is roughly the saturation point. TODO: turn this into a CVAR. 3. Limit per target issued operations to 50. This will give the target a better chance to process events without being overwhelmed by a single process. TODO: turn this into a CVAR, also. 4. Allocate more buffer space for incoming control messages. Observed results, especially with larger messages, showed that more buffer space cuts down on flow-control events. Signed-off-by:
